ProGuard starts despite minifyEnabled false, what could be the reason?

Question

Android

The configuration explicitly says not to run ProGuard, but it still starts!

integration {
minifyEnabled false
versionNameSuffix "-int"}

Where else to look?
You can see what starts from this step:
:control:transformClassesWithMultidexlistForIntegration
